Changing banks

Enrollment in this portal points payments at a specific bank account. When you switch banks, log back in and update the deposit account for every payer listed above, payers do not share bank changes with each other, even inside the same portal. Keep the old account open until you see deposits land in the new one. Full playbook: Switch banks without missing a payer deposit.
